Worked practice questions

Among alcohols, the reactivity order with HX (e.g. HCl) is:

  1. 1° > 2° > 3°
  2. 3° > 2° > 1° (tertiary fastest via stable carbocation)
  3. All equal
  4. Aromatic > aliphatic
Show answer and solution

Correct answer: B. 3° > 2° > 1° (tertiary fastest via stable carbocation)

S$_N$1 mechanism: 3° alcohol → 3° carbocation (most stable due to hyperconjugation and inductive effects). 3° > 2° > 1°. Methanol/ethanol need more forcing conditions or different mechanism (S$_N$2).
